초록

잎새버섯으로 준비된 물 추출물과 유기용매 분획물의 혈전용해활성과 트롬빈저해활성, acetylcholinesterase 저해활성, 항산화활성 및 면역활성을 확인하였다. 물 추출물과 물 분획물은 각각 1.55 plasmin unit와 0.85 plasmin unit의 높은 혈전용해활성을 나타내고, 물 분획물과 에틸 아세테이트 분획물은 76.43%와 72.59%의 트롬빈저해활성을 나타냈다. 클로로포름 분획물과 헥산 분획물이 95.14%와 94.74%의 높은 acetylcholinesterase 저해활성을 나타냈으며, 부탄올 분획물과 물 추출물이 94.47%와 91.04%의 항산화활성을 나타냈다. 부탄올 분획물과 물 분획물이 각각 2배 이상의 높은 면역기능활성을 나타냈다. 실험 결과로부터 잎새버섯의 분획물은 높은 혈전용해활성, 트롬빈 저해활성, acetylcholinesterase 저해활성 및 면역 기능활성을 나타내 심혈관계 질환과 치매의 예방 및 면역 기능강화를 위한 기능성식품 개발에 이용할 수 있을 것으로 사료된다.

This study was performed in order to analyze the fibrinolytic, thrombin inhibitory, anti-oxidative, acetylcholinesterase inhibitory, and immuno-enhancing activities of the water extract and solvent fractions isolated from Grifola frondosa. Fibrinolytic activity was analyzed using the fibrin plate method, and thrombin inhibitory activity was assayed using the substrate H-D-Phe-piparg- pna. Anti-oxidative activity was estimated using the DPPH assay, and AChE inhibitory activity was measured using the spectrophotometric method. Immuno-enhancing activity was examined using the nitric oxide (NO) production in RAW 264.7 macrophage cells. Cell viability was determined using the MTS assay. Fibrinolytic activities were the highest in water extract (1.55 plasmin units/mL) followed by water fraction (0.85 plasmin units/mL). The thrombin inhibitory activities of the water and ethyl acetate fractions were determined to be 76.43% and 72.59%, respectively. The acetylcholinesterase inhibitory activities of chloroform and hexane fractions exhibited values of 95.14% and 94.74%, respectively. The butanol fraction showed the highest anti-oxidative activity at 94.47%. Anti-proliferating activity against Raw 264.7 cells showed no cytotoxicity. The production of NO in Raw 264.7 cells increased up to 2-fold by adding the water fraction compared to the untreated control. These results suggest that Grifola frondosa may serve as a useful functional food for the enhancement of immune function and the prevention and therapy of cardiovascular diseases.
